My wife and I recently visited the LOC. We had an opportunity to sit in the stunningly beautiful reading room where I read the Encyclopedia of Spies, of all things. It really was an interesting book and when it was time to leave I asked the librarian if the collection was digitized so I could finish reading it. He didn't know so tonight I finally got around to searching the digitized collection of the Library of Congress. What I did find was a very large collection of astronomy related material, both fact and fiction, including a large number of photographs and movies available for download. I think this will turn out to be very interesting.
